Description
The Japanese butterfly ray is a butterfly ray (Gymnuridae) from coastal waters of the northwest Pacific, off East Asia. The species grows to about 1 metre across and has a very broad, diamond-shaped, flattened, brown-grey disc that is far wider than long, and a short tail with a small venomous spine. As a bottom-dweller it lies half-buried on sand and mud bottoms and hunts small fish, shrimp and molluscs. The tail spine can cause a painful wound; remain cautious.
